Linux + is it correct to create volume using LVM over physical disks when disks size are huge

Our Goal is to use huge storage as 200TB for Kafka machine

In order to achieve this Goal , we create volume using LVM over 4 physical disks in RAID10 , when each disk size is 50T ,

Note – each disk as sdb/sdc/sdd/sde is actually RAID10 , when each RAID10 is holding 12 disks

In our kafka server we have 4 disks ( example from lsblk )

sdb                  8:16   0   50T  0 disk 
sdc                  8:32   0   50T  0 disk 
sdd                  8:48   0   50T  0 disk 
sde                  8:64   0   50T  0 disk 

So we wrote the following procedure:

We combine the disks /dev/sdb and /dev/sdc. and /dev/sdd and /dev/sde , by adding them to the same volume group.- DB_vg

vgcreate DB_vg /dev/sdb /dev/sdc /dev/sdd /dev/sde

we create logical volumes ( we are using here 200T size )

lvcreate -L200T -n DB_lv DB_vg

We create the XFS filesystem

mkfs.ext4  -j -m 0  /dev/DB_vg/DB_lv -F

We create folder , in order to mount the LV to this folder

mkdir /var/lib/kafka_broker

mount /dev/DB_vg/DB_lv /var/lib/kafka_broker

from df -h , its should looks like this ( example )

/dev/mapper/DB_vg-DB_lv  200T   61M  200T   1%  /var/lib/kafka_broker

from lsblk

sdb                   
└─DB_vg-DB_lv 253:4    
sdc                   
└─DB_vg-DB_lv 253:4   
sdd                  
└─DB_vg-DB_lv 253:4    
sde                  
└─DB_vg-DB_lv 253:4  

from blkid

blkid | grep LVM2_member
/dev/sda2: UUID="Y5MbyB-C5NN-hcPA-wd9R-jmdI-02ML-W9qIiu" TYPE="LVM2_member"    <-- sda2 is the OS
/dev/sdc: UUID="mtg8CY-b3j9-K1qZ-CRTV-SZum-gDx3-lbm4ZX" TYPE="LVM2_member"
/dev/sdb: UUID="MvfzqO-PV8N-dror-psl4-PfUf-7coa-6cb8lQ" TYPE="LVM2_member"
/dev/sdd: UUID="C4n63l-Uk3E-D65G-WcgI-xic2-cJLi-eSTUAa" TYPE="LVM2_member"
/dev/sde: UUID="d743Xp-eDxr-Dygk-HGgy-Dh9c-K3cx-kHtyqo" TYPE="LVM2_member"

So now we can use the LV /dev/mapper/DB_vg-DB_lv that mount to /var/lib/kafka_broker folder

and we can use the folder /var/lib/kafka_broker as storage with 200T for kafka broker machine

My Questions are:

1. is it safe? to use huge storage that created by LVM using 4 Huge disks?

2. can we create XFS filesystem when storage is around 200T size?

3. am I right about my procedure or maybe I am missing something?
